Framework for slideshow object

ABSTRACT

A system in accordance with the present invention may include one or more processors, memory that receives instructions from the one or more processors according to a clock operating at a frequency, one or more programs stored in the memory, with instructions to: define a layer, wherein the layer comprises one or more effects; associate media content with the layer; aggregate the layer with one or more other layers; and, assemble the aggregated layers.

This application claims the benefit and priority of the U.S. Provisional Patent Application No. 61/193,851 filed on Dec. 30, 2008, which is hereby incorporated by reference.

FIELD OF INVENTION

The present invention relates generally to the field of media presentations and, in particular, to authoring, rendering, viewing, exporting, and sharing media presentations.

BACKGROUND OF INVENTION

Current media presentation applications offer features for creating slides and manually customizing the ways in which a set of slides, i.e., a slideshow/media presentation, is played. Such applications also offer features for attaching themes to slideshows, where such themes may affect the appearance and general behavior of the slideshows when played. In addition, such applications further offer features such as customizing slide colors, customizing transition behavior, customizing transition delay, and manually adding clip art/image/audio/video files to one or more slides in a slideshow. These applications also permit basic sequential transition, forward or backward, and from one slide to another in a slideshow containing more than one slide. A user may customize the time that one slide should be viewed prior to the application invoking a transition to another slide, which may further have a custom viewing time associated with it as well. However, current media presentations applications do not provide a feature for authoring media presentations, comprising: defining a layer, wherein the layer comprises one or more effects; associating media content with the layer; aggregating the layer with one or more other layers; and assembling the aggregated layers. Moreover, current media presentation applications also do not provide a feature for dynamically profiling a slideshow soundtrack based on various criteria like beats per minute (BPM), rhythmic strength (RS), harmonic complexity (HC), and/or root mean square density (RMS or RMS strength). Such criteria, when profiled intelligently, may be further used to select appropriate effects and assemble such effects in useful ways applicable to a slideshow. Further, such effects could be customized according to durations, in/out points, and transitions in-sync with audio alone or the audio of a video. Finally, current media presentation applications do not provide features for automatic, as well as user-defined, authoring, rendering, exporting, and sharing media presentations/slideshows in an easily integrated modern platform.

SUMMARY OF THE INVENTION

Accordingly, the present invention is directed to a system and method for authoring, rendering, exporting, and sharing media presentations that substantially obviates one or more problems due to limitations and disadvantages of the related art.

An embodiment of the present invention provides a computer-implemented method for authoring media presentations, comprising: defining a layer, wherein the layer comprises one or more effects; associating media content with the layer; aggregating the layer with one or more other layers; and assembling the aggregated layers.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, a system comprises one or more processors; memory; one or more programs stored in memory, the one or more programs comprising instructions to: define a layer, wherein the layer comprises one or more effects; associate media content with the layer; aggregate the layer with one or more other layers; and assemble the aggregated layers.

In another aspect, a computer-readable storage medium stores one or more programs configured for execution by a computer, the one or more programs comprising instructions to: define a layer, wherein the layer comprises one or more effects; associate media content with the layer; aggregate the layer with one or more other layers; and assemble the aggregated layers.

In yet another aspect, a computer program product stores one or more instructions for execution by a computer, the one or more instructions comprising: creating a document; associating one or more layers to the document, wherein the layers are organized within the document; associating one or more effect containers with the layers, wherein the effect containers are linked and are organized within the layers; associating one or more effects with the effect containers; and assembling the effects, effect containers, and layers logically within the document.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

FIG. 1 illustrates an exemplary embodiment of an application in accordance with the present invention. The exemplary embodiment of an application 1000 comprises a document 1001, a set of controls 1002 for controlling/manipulating the document 1001, an edit layers and effect containers region 1003 (e.g., steps 6001, 7001), a background layer 1004 with effect containers and effects associated with the effect containers, a foreground layer 1005 with effect containers and effects associated with the effect containers, a text typewriter 1006 for associating text with one or more effect containers/effects/slides, a document length 1007 indicator, a select media content menu 1008 (e.g., steps 6002, 7002), a main effects library 1009, a documents selection menu 1010 for selecting among available documents, one or more effects 1011 (which may be available according to a filter criteria) within the main effects library 1009, a subset of the main effects library 1012, a gap variable 1013 for separating an effect or effect container (with one or more effects and slides) from the next effect or effect container using a gap, a transition variable 1014 for separating an effect or effect container (with one or more effects and slides) from the next effect or effect container using a transition, and an effect style 1015 (also, name or property). The exemplary embodiment of an application 1000 illustrates a use of the application 1000 to create a document 1001 (e.g., steps 6004, 7004) using a background layer 1004, a foreground layer 1005 (additional background/foreground layers may also be added to the document but may not be illustrated in FIG. 1) (e.g., steps 7008, 7009), customized gaps 1013 and/or transitions 1014 separating effect containers. Effect containers may comprise, for example, one or more effects from, for example, the main effects library 1009 or the subset of the main effects library 1012; and, effects may further comprise one or more slides like, for example, images, movies, audio, text (e.g., a string with font information that may determine how text will look and feel), and other media content (e.g., steps 6002, 7002, 7006, 7012, 7013). Effects may determine how the image and its surroundings will appear on a screen/display during play (e.g., an image may be displayed according to “book theme,” where the effect would be the feature/component for determining how the photos may be laid out or organized on-screen; an effect may store/pass information related to how a photo would bounce around on a screen; or, an effect may also store/pass information related to text, where the text may be added or associated with a slide, effect, layer, or document of a slideshow/media presentation). Further, effects may be filtered according to media content type using the select media content menu 1008. For example, images, video, audio, text, and captions may be used to filter effects accordingly. Meaning, the relevant effects associated with each of the foregoing types of media content may be displayed accordingly upon invocation of the respective menu item from the select media content menu 1008. Details regarding effects may be displayed in the effects style 1015 section, which may be positioned beneath each respective effect container, and corresponding to a presently active effect, in the effect containers region 1003.

In some embodiments, the exemplary embodiment of an application 1000, and its features/components, may be implemented by one or more modules/engines (FIG. 3A, reference numerals 3020-23) executed using an exemplary system 4000 (FIG. 4) with a central processing unit (CPU) 4001 (and, alternatively, multiple CPUs), memory 4002 for storing data (e.g., instructions from an operating system 4007 or one or more programs (e.g., 4008, 4009)) to be fetched by the CPU for execution, a display device 4003 for displaying the exemplary application 1000 using a graphics module to a display screen, a network interface card (NIC) 4004 for sending and receiving data over a wired or wireless communications network, local storage 4006 for storing media content and other data (e.g., an operating system 4007, the exemplary embodiment of an application 1000, other applications, etc.), and auxiliary device(s)/component(s) 4005 (e.g., TV (or, other display), portable storage, portable media player, etc.), which may all be connected via a bus for sending and receiving data according to a frequency (e.g., synchronous or asynchronous).

In some embodiments, the features/components of the application 1000 may be described as follows. The document 1001 (also, FIG. 3, reference numeral 3001) is the top level object of the media presentation/slideshow that may be created (e.g., steps 6004, 7004) using the exemplary application 1000. The document is the object that may comprise: all of the custom/default layers 1004, 1005 (also, FIG. 3, reference numeral 3002) (e.g., steps 6003, 7003, 7010), effect containers such as, for example, those within the effect containers region 1003 (also, FIG. 3, reference numeral 3003); effects such as, for example, those within the effect containers (also, FIG. 3, reference numeral 3004); gaps 1013 or transitions 1014 for separating or linking effects, respectively (also, FIG. 3, reference numeral 3012); slides such as, for example, the images of FIG. 1 or other media content as described above (also, FIG. 3, reference numeral 3005, 3010) (e.g., step 6002, 7002); frames 3006; a document/layer/effect stack 3007; a layer/effect/slide/filter stack 3011; a playlist 3008; an animation path 3014; a song 3009; a keyframe 3015 (which may, for example, be one dimensional (1D) 3016, two dimensional (2D) 3017 or a vector (3018)); filters 3019; a layer/effect container/effect/slide/filter stack 3013; and, any other possible combination of the aforementioned. Moreover, a document may contain layers that may be stacked/placed one on top of another to provide the media presentation/slideshow with an added level of flexibility in what is available for actual display (e.g., steps 6003, 7003, 7010). Accordingly, the application supports the presentation of less than all of the available layers. Stacking may involve a process, for example, of logically associating, or linking, layers. That is, a background layer 1004 may be considered the lowest level layer in a stack of layers, followed by a foreground layer 1005 and a plurality of other foreground layers, all of which would be logically associated according to their position from, for example, background layer 1004, or from each other foreground layer. During display/play of a document such as, for example, document 1001, the layers would be displayed/played according to their respective positions in the stack (logical associations). The next feature/component is the layers 1004 (background), 1005 (foreground) (also, FIG. 3, reference numeral 3002) within a document 1001 (also, FIG. 3, reference numeral 3001) (e.g., steps 6001, 7001). Each layer 1004, 1005 of a stack of layers (e.g., aggregated layers; steps 6003, 7003) within a document can be positioned, sized, and rotated using the exemplary application 1000. Further, each layer 1004, 1005 may also have a custom audio file/track (or, alternatively, a set of audio files/tracks, or other media content) associated with it and other layers 1004, 1005, thus, providing a media presentation/slideshow with multiple audio files/tracks during presentation (e.g., steps 6002, 7002). Each layer 1004, 1005 may also contain effect containers (like, for example, those illustrated in the effect containers region 1003) (e.g., steps 6002, 7002), which may be linked together in a layer using transitions 1014 (also, FIG. 3, reference numeral 3012) or separated from one another using gaps 1013 (or, alternatively, some other effect separation variable like, for example, random separation/transition, or a combination of gaps and transitions, etc.) (e.g., 7005). Transitions 1014, which through visual action/expression may create the appearance that two effect containers are linked together, may be able to provide a rather “fluid” (or, alternatively, a “non-fluid”) experience between effect containers when presenting a media presentation/slideshow. For example, transitions may be the visual action/expression of a page flipping, a slide dissolving, a slide being pushed along in any direction, a cube breaking apart (or, being assembled), a page rolling for the purpose of unveiling/hiding contents, a puzzle being assembled (or, disassembled), or any other type of visual action/expression applied to an effect container or slide and capable of being rendered on a display device. Slides in the exemplary application may be the actual image, movie, text, or other media content that may be within an effect, which may be within an effect container (e.g., steps 6002, 7002). Slides may have frames applied as an added layer (e.g., on top), where a frame may be a visual element/expression such as, for example, making an image appear as if it was taken using an instant photo camera (e.g., Polaroid®), is part of a filmstrip, has a solid/dashed/shadowed/other border surrounding it, or other type of frame-related visual element/expression. Further, each slide may have an animation path 3014 that may determine which part of a slide image, movie, text, or other media content, is actually displayed/played; similarly, an animation path 3014 associated with the slide may cause a panning/zooming effect to be executed on the image, movie, text, or other media content, where the panning/zooming may occur within the effect of the slide. As applied to a layer, a user may also customize an animation path 3014 via the exemplary application 1000 to, for example, smoothly transition a layer's rotation from around zero (0) degrees all the way to three hundred sixty (360) degrees, over a default or custom period of time (e.g., steps 6002, 7002). In some embodiments, transitions 1014 may have durations associated with them to determine how long the transitions are played. The transition duration may be subtracted directly from the total duration of the effect containers separated/divided by the transition. For example, when transitioning from an effect container with a three (3) second duration to another effect container with a three (3) second duration, that is, having a six (6) second total duration, using a transition with a one (1) second duration, the effect containers may only be played for a total of five (5) seconds (i.e., the total six (6) second duration of the effect containers minus the one (1) second transition display/play duration leaves five (5) seconds of display/play duration for the effect containers).

In some embodiments, effect containers may be able to determine the order that images (or, alternatively, other media content) associated with a layer (e.g., steps 6002, 7002) are presented during a media presentation/slideshow. Such a determination may be based according to characteristics associated with the images (or, alternatively, other media content) (e.g., steps 6004, 7004). The characteristics may comprise a resolution, size, quality indicator, dots-per-inch, frames per second, window size, bit error rate (BER), compression type, or some other media content characteristic. The exemplary application 1000 may execute this process of assembling the layers (e.g., steps 6004, 7004) either manually or according to algorithms processing the characteristics and other layer-related data (described above). Further with respect to effect containers (e.g., a container or group of effects), multiple effects may be transitioned as one set into the next effect container. For example, effect containers are necessary in order for different text to be displayed on top of different effects. In some embodiments, from an implementation viewpoint, the effect containers permit the logical/physical grouping of different effects and link each of the effects to their respective different text, which is to be displayed on top of each respective effect. Each effect container may, for example, further contain a variable for storing a specific duration for determining how long each of the effects associated with an effect container (or, alternatively, “within” the effect container) are displayed/played.

In some embodiments, a keyframe 3015 (which may, for example, be one dimensional (1D) 3016, two dimensional (2D) 3017 or a vector (3018)), may be used by an animation path 3014 to guide or instruct the rate at which animation path 3014 should operate. Meaning, the higher the value of a keyframe 3015, the increased rate the animation path 3014 may operate (e.g., a faster pan-zoom effect or a faster layer rotation), and the lower the value of a keyframe 3015, the lower rate the animation path 3014 may operate at (e.g., a slower pan-zoom effect or a slower layer rotation). A 1D 3016 keyframe may be a keyframe that animates a property that has one value like, for example, a rotation angle. A 2D 3017 keyframe may be a keyframe that animates a property that has more than one value like, for example, a position (x-axis point, y-axis point) or a size (width/length, height). And, a vector 3018 keyframe may be a keyframe that animates a property that has more than two values like, for example, colors that manipulate the different values of their constituent color components (e.g., red, green, blue, alpha).

In some embodiments, filters 3019 operate as visual elements that are applied to a layer, effect container, effect, or slide. A filter 3019 may be, for example, a shadow, blurred image, or some other compatible visual element capable of being applied to a layer, effect container, effect, or slide (e.g., steps 6002, 7002).

In some embodiments, a playlist 3008 associated with a document 1001 may contain a list of songs (e.g., steps 6002, 7002). The playlist 3008 may organize songs such that they are played in a specific order, determined manually by a user of the exemplary application 1000, or automatically through the exemplary application 1000. An automatic playlist may be created according to song genre, file characteristics (e.g., type, size, date, etc.), or according to the feature for dynamically profiling a slideshow soundtrack based on various criteria like beats per minute (BPM), rhythmic strength (RS), harmonic complexity (HC), and/or root mean square density (RMS or RMS strength). The songs (e.g., a reference to a playlist) may be stored in digital format in local storage 4006 or on an auxiliary device/component 4005 that communicates with the system 4000 through a communications protocol or standard. The songs may be stored in a single file (or, other logical/physical data aggregator) or many files. In addition to songs, a playlist 3008 may contain other compatible media content like videos with audio content (which, for example, may be parsed from the video file into an individual song/audio file, or playlist). To associate a playlist, song/audio file, or any compatible media content with a document 1001, the user may select it/them from the select media content 1008 menu and drag the respective playlist, song/audio file, or other compatible media content, via the exemplary application 1000, into the effect containers region 1003 (see, for example, the reference to “Drag Audio Here” in the exemplary application 1000) (e.g., steps 6002, 7002). Songs may be played in the background while a document is being displayed/played, or they may, alternatively, be associated with foreground layers or effects that may be organized on top of another, thus, enabling the songs to be switched in coordination with the various switching (e.g., via gaps or transitions) from one layer or effect to another (e.g., steps 6004, 7004). Further, songs may, according to a default setting, start and stop playing based on the start and stop times that may be given from a media player or media management application. The user of the exemplary application 1000 may, however, define a custom start or stop time via a song (or, playlist) menu option of the application 1000.

FIG. 2 illustrates features of an exemplary embodiment in accordance with the present invention. As illustrated, the exemplary embodiment of an add effects container region 2000 (similar to that of 1003; FIG. 1) contains three layers, the first is a background layer 2001, and the second and third are foreground layers 2002 and 2003 (e.g., steps 6001, 7001, 6002, 7002, 7008, 7009). Effect containers are illustrated as 2004, 2005, and 2006 in the background layer 2001. The foreground layers 2002 and 2003 also contain effect containers. Each effect container has effects with slides/media content within, such as illustrated by the slides (e.g., images) 2011 and 2013 in the second foreground layer 2003. Moreover, gaps 2007, 2008, 2009 separate effect containers in foreground layers 2002 and 2003. Also, transition 2010 separates (or, “link”) effect containers in the foreground layer 2003. Further, an effects style 2012 is illustrated for the second effect container of the second foreground layer 2003 (e.g., step 7007). The effects style may display one or more styles or properties such as, for example, a media presentation order, a thumbnail, a layout, a position, a size, a zPosition (e.g., the position in a three-dimensional (x, y, z) orientation), a base period, an effect presets, an effect settings overwrite, a matching layer duration, a recommended effect duration, a transition preset, a transition settings overwrite, a recommended transition duration, a filter preset, a filter preset criteria, a filter likelihood, a gap likelihood, a layer importance, a slide filter preset criteria, a slide frames criteria, an automatic filter likelihood, and a support per-slide customization (e.g., step 7014). Other styles or properties may also be displayed at 2012 or in another section of the graphical user interface of the exemplary application 1000 or at the container region 2000 like, for example, a background color and an automatic filter mode (e.g., step 7015). The styles or properties may apply to the effects, effect containers, layers, and/or document, and may further be customized for each of the foregoing or inherited from each other, whether set by default or is customized (e.g., step 7007).

FIG. 2A illustrates features of an exemplary embodiment in accordance with the present invention. The exemplary embodiment 2000A illustrates an effect container 2020 with a phaseIn effect 2021, a main effect 2022, and a phaseOut effect 2023. Also, the blurred image (or, movie or other media content) shown behind the “main” text illustrates an exemplary instance of a blurred effect during the main effect 2022 phase of the effect container 2020. The phaseIn effect 2021 (e.g., like a fade-in) may be used, for example, to build a single/multi-slide layout, where as the phaseOut effect 2023 (e.g., like a fade-out) may be used, for example, to tear down/away or remove a single/multi-slide layout. Thus, the phaseIn 2021, main 2022, and phaseOut 2023 effects may be applied to a single slide or to multiple slides. Furthermore, there may be a time associated with each phaseIn effect 2021, main effect 20222, and phaseOut effect 2023. The time spent on each slide of a multi-slide effect may be equally divided among the individual slides (e.g., total effect time divided by the total number of slide, and adjusted accordingly) or apportioned in a custom manner to each individual slide.

FIG. 3 is a block diagram illustrating framework features of an exemplary embodiment in accordance with the present invention. In some embodiments, the exemplary application 1000 executing on the exemplary system 4000 may cause the CPU 4001 to execute instructions for creating an electronic structure (e.g., 3000) for storage in memory 4002, local storage 4006, or on an auxiliary device/component 4005, such instructions may comprise: creating a document (e.g., 3001); associating one or more layers (e.g., 3002) to the document, wherein the layers (e.g., 3002) are organized within the document (e.g., 3002); associating one or more effect containers (e.g., 3003) with the layers, wherein the effect containers (e.g., 3003) are linked and are organized within the layers (e.g., 3003); associating one or more effects (e.g., 3004) with the effect containers (e.g., 3004); and assembling the effects (e.g., 3004), effect containers (e.g., 3003), and layers (e.g., 3002) logically within the document. The application features 3000-3019 are referred to and described in detail herein, and in view of the exemplary application 1000, which may be executed, for example, on the exemplary system 4000.

FIG. 3A is a block diagram illustrating framework features of an exemplary embodiment in accordance with the present invention. The framework features 3000A may comprise framework module units (or, modules) such as, for example, a core 3020, a producer 3021, a renderer 3022, and an exporter 3023. The features 3000A may implement the structure/architecture of the exemplary application 1000, and may be executed, for example, using a system like that illustrated in FIGS. 4-5.

In some embodiments, the core 3020 module may be considered the low-level data structure module and it may, for example, perform routines for representing how a slideshow/media presentation document is constructed, and contain the necessary information for accurately representing a slideshow/media presentation document according to features, many of which are described herein (e.g., steps 6001-6003, 7001-7003). Some of those features may include, for example, features related to timing (e.g., gaps 1013, transitions 1014), positioning (e.g., background layer 1004, foreground layer 1005, effects of effect containers 2004-2006, slides 2011, filters 3019, text 3010), sizing (e.g., keyframe 3015, animation path 3014, as well as their interaction), and files (e.g., songs 3008, playlists 3009).

In some embodiments, the producer 3021 may be considered the module for creating how a slideshow will look and feel (e.g., steps 6002-6003, 7002-7003), performing several analyses related to media content (e.g., images, audio, video of layers, effect containers, effects, and slides) (e.g., step 7016), and automatically assembling slideshows/media presentations according to data that may result from the analyses (e.g., steps 6004, 7004, 7011). The several analyses (e.g., step 7016) may include analysis of characteristics related to layers, effect containers, effects, and slides. Such characteristics may include, for example, layer type (e.g., background 1004, foreground 1005), layer number (e.g., position in relation to the background-most layer 1004), number of effect containers, length of gaps 1013 and transitions 1014, type of transitions 1014, type of effects, number of effects, number of slides, type of slides, document length 1004, user preferences (e.g., for ordering layers, effect containers, effects, slides), audio analyses, video analyses, or other similar characteristics. After performing the several analyses using, for example, the producer 3021, the resulting data from the several analyses may be processed by the producer 3021, the core 3020, the renderer 3022, the exporter 3023, or other module (e.g., step 7017). The producer 3021 may, for example, interface with and utilize the application programming interfaces (API) of frameworks like, for example, browsers or QuickTime® to gather such information as thumbnail data and resolutions for images, as well as audio or video durations or other characteristics. The gathered information may then be processed by the producer 3021 in accordance with one or more general/specific algorithms (or, other analytical methods) and then used by the producer 3021 (or, other module with which the producer 3021 may call), for example, to automatically assemble a slideshow or media presentation document (e.g., 7011). The producer 3021 may further, for example, assemble a document via core 3020 for play/display using the features of renderer 3022, by accessing photos and coupling such photos with a style (e.g., 1015). In addition, the producer 3021 may also, for example, perform audio analysis functions on songs 3009 or a set of songs (playlist 3008) using such analysis like, for example, beat detection/mapping. The producer 3021 may also keep track of available styles (e.g., 1015), effects 3004, transitions 3012, and frames 3006.

In some embodiments, the renderer 3022 may be considered the play/display module. The renderer 3022 may receive slideshow/media presentation data from, for example, the core 3020 and producer 3021 and may render such data such that it may be sent to a graphics card or other display device (or interface) (e.g., 4003). The renderer 3022 may interface with QuickTime® media player (e.g., the framework of QuickTime® media player) or another compatible application (or, framework) for audio/video decoding. In addition, the renderer 3022 may also interface with a composer-type application for actual rendering (e.g., of the slides), and the same or another similar application for applying filters 3006.

In some embodiments, the exporter 3023 may be considered the sharing module. The exporter 3023 may, for example, use renderer 3022 to export the slideshow/media presentation document to different formats (e.g., file formats) like those supported by QuickTime® or other similar applications. The exporter 3023 may, for example, obtain movie frame-type data from renderer 3022 and add it to a movie-type file. When the exporter 3023 is finished retrieving data for each movie, the slideshow/media presentation document would be available for access and sharing through the exemplary application 1000 or other applications that may access or handle the document in its final format.
